  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  Risk of fire and explosion on contact with incompatible substances. See Chemical Dangers.  NO open flames. NO contact with strong oxidizing agents. NO contact with hot surfaces.  NO contact with incompatible materials: See Notes.  Use water spray, powder, foam, carbon dioxide.   

 PREVENT DISPERSION OF DUST! AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS PREVENTION FIRST AID
Inhalation See Ingestion.  Use closed system and ventilation.  Fresh air, rest. Seek medical attention if you feel unwell. 
Skin   Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes   Wear face shield or eye protection in combination with breathing protection if powder.  Rinse with plenty of water (remove contact lenses if easily possible).

ARSENIC ICSC: 0013
PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
BRITTLE GREY METALLIC-LOOKING CRYSTALS. 

Physical dangers
No data. 

Chemical dangers
Upon heating, toxic fumes are formed. Reacts violently with strong oxidants and halogens. This generates fire and explosion hazard. Reacts with reducing agents. This produces toxic and flammable arsine gas (See ICSC 0222). 

Formula: As
Atomic mass: 74.9
Sublimation point: 613°C
Density: 5.7 g/cm³
Solubility in water: none
Auto-ignition temperature: 180°C  


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. 

Effects of short-term exposure
The substance may cause effects on the gastrointestinal tract. This may result in severe gastroenteritis, loss of fluids and electrolytes, cardiac disorders, shock and convulsions. Exposure far above the OEL could cause death. The effects may be delayed. Medical observation is indicated. 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. 

Effects of long-term or repeated exposure
The substance may have effects on the skin, mucous membranes, peripheral nervous system, liver and bone marrow. This may result in pigmentation disorders, hyperkeratosis, perforation of the nasal septum, neuropathy, anaemia and liver impairment. This substance is carcinogenic to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development. 


OCCUPATIONAL EXPOSURE LIMITS
MAK: skin absorption (H); carcinogen category: 1; germ cell mutagen group: 3A 

ENVIRONMENT
The substance is toxic to aquatic organisms. It is strongly advised not to let the chemical enter into the environment. 

NOTES
The substance is combustible but no flash point is available in literature.
Depending on the degree of exposure, periodic medical examination is suggested.
Do NOT take working clothes home.
